Function parry3d::transformation::utils::push_arc_and_idx

pub fn push_arc_and_idx(
    center: Point<Real>,
    start: u32,
    end: u32,
    nsubdivs: u32,
    out_vtx: &mut Vec<Point<Real>>,
    out_idx: &mut Vec<[u32; 2]>
)

Pushes to out_vtx a set of points forming an arc starting at start, ending at end with revolution center at center. The curve is approximated by pushing nsubdivs points. The start and end point are not pushed to out_vtx.

ALso pushes to out_idx the appropriate index buffer to form the arc (including attaches to the start and end points).
